-12 AN Female Regulator (AN fitting not included)

Manufactured from 6061-T6/651 aluminum and color anodized. This regulator was designed to be mounted directly to a male -12 AN fitting (fitting not included). Like all our regulators, this one is infinitely adjustable, there are no springs or shims to "fool" with. Simply loosen the jamb nut and turn the head to increase or decrease the vacuum set point.

All our regulators have screened inlets to keep dirt out of our pumps and out of your engine. There are two major benefits to mounting our vacuum regulator directly to your pump. First, when the regulator set point is reached, ambient air is drawn directly into the pump helping it run cooler. And the other, by placing the regulator "outside" the crankcase area, the excess air the regulator is bypassing will no longer be passing thru the engine to the pump. It now flows directly into the pump, reducing the possibility of oil being scavenged from the engine.
